Pros:
The Massacre! This is course blessed with plenty of elevation changes and some of the best trees that act as disc golf bunkers I have ever seen. The front nine starts with an uphill shot followed by a nice downhill shot and both are well done and fun to play. The tree bunkers act as a score filter by weeding out non accurate drives. Trying to pitch out of these things is a nightmare and rightfully so, so of course accuracy is much more important than distance. Tons of variety here as far as doglegs, hyzer and anhyzer throws and on some of the more downhill throws landing zones need to be identified and hit off the tee. Hole 9 is a little RHBH hyzer putter throw with serious danger if you hyzer too much and your disc may fall or roll a hundred feet into the snake river.The back nine is a little more 'wild' than the front and the canyon shot early one kind of tells you that. The canyon shot isn't very far and most disc golfers can reach it but it's always fun throwing downhill. The next hole which the tee pad is right on a cliff and a little freaky for those of us with a fear of heights is a really fun albeit short straight shot on top of a ridge that acts sort of like an island green. When you reach the top of all these little peaks and ridges you can see the snake river and all its glory including the mountains and trails around it.
Cons:
The footing here is not ideal as it's very uneven and you find holes, roots, branches, sticks, rocks, etc. all over the course and twisting an ankle out here would not be a fun experience, not that it is anywhere but you know what I mean. The walk down the large hill down into the canyon is what us old school hikers call a goat trail and not in a good way; bad footing, very steep, no steps or switchbacks, almost scrambling steep wise and when you're carrying a bag and/or a rolling cart it's quite difficult to maneuver. Speaking of rolling carts this is NOT a cart friendly course. Although we managed the cart if I were to do it over again I would have brought one bag instead of a bag and a cart for the two of us. The tee pads are dusty, gravel and many times slippery or just plain uncomfortable to throw on. There are a few fly pads out here but only on the holes throwing off near a cliff IIRC. By the way it gets really windy here and there is a wind farm just across the freeway from here so keep that in mind.
Other Thoughts:
Certainly not a course for the faint of heart or just getting into disc golf. Luckily there is another course on site that is a more friendly to n00bs short 9 hole course that wraps around the information center. If you're gonna play this course it's $7 day use or $10 for a seasonal Idaho state parks pass that is available at your local DMV - don't worry it's Idaho the DMV takes 10 minutes to get through most of the time. This is a fun course that has a mountain golf kind of feel without being in the mountains. I recommend it if driving by or camping and you should check out the cool history information at the center or drive to the end of the gravel road near the Lewis and Clark trail and check that out too.
